murmur-mim Specification of Ilctters Patent.

Patented May 17, 19 21.

Application filed June 11, 1920. Serial No. 388,154.

To aZZ whom it may concern Be it known that I, EDWARD D. HISCOCK, acitizen of the United States, residing at Odell, in the county of HoodRiver and State of Oregon, have invented certain new and usefulImprovements in a Carbureter- Heater, of which the following is aspecification.

This invention relates to internal combustion engines and moreparticularly to vaporizers for use in connection therewith.

The object of the invention is to provide an attachment for applicationeither to a carburetor or to the intake manifold of a gas engine tofacilitate the starting of the explosive engine by supplying a highlyexplosive heated mixture.

Another obiiiect is to provide a simple and efficient attac mentof thischaracter to insure the prompt starting of cold gas englnes, beingconstructed so as to provide suflicient heat to supply ample primingfluid to start a heavy engine when cold.

With these and other objects in view, the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims, and in the drawings.illustrative of the preferred embodiment of the invention.

In the accompanying drawings:

Figure 1 represents a perspective view of the attachment constitutingthis invention. Fig. 2 is a transverse section thereof.

In the embodiment illustrated the attachment comprises a substantiallyovate casting 1 having a bore 2 extending longitudinally therethroughand provided at one end with an attaching pipe or coupling 3 while itsopposed end is bent upwardly to form a receivlng cup 4. The coupling 3may be of any desired construction and is designed for attachment to theair intake pipe of a carbureter or to be tapped into the intake manifoldof a gas engine. The bore extending through thecasting is preferablysomewhat larger than the discharge openings at the end thereof.

Arranged under and extending laterally beyond opposite sides of the bodyportion 1 of the attachment is a tray 5 secured to or cast integral withthe casting and which is designed to contain gasolene or otherinflammable fuel for heating the casting to v p ri e f el o be fed throgh sa d castin It is of course understood that if thedevice is to beremovably attached to the manifold and only used for starting a coldengine it will be necessary to provide a closure for the hole in themanifold which is made to receive the pipe 3. When the device is appliedto the carburetor all that is necessary is to insert the gas dischargeend 3 in the air intake pipe of said carbureter and hold the device inthis position until the engine has been started.

In the use ofthis attachment the end 3 having been inserted in themanifold opening or the air intake of the carburetor gasolene is placedin the tray 5 and ignited which will thoroughly heat the casting 1. Fuelin the form of gasolene is then introduced through the receiving cup 4and in its passage through the casting 1 will be thoroughly heated andvaporized before entering the carburetor or manifold. The cranking ofthe engine will operate to suck into the cylinders this heated vaporizedfuel in addition to that supplied by the carbureter thus producing ahighly explosive mixture which will insure qulck starting of the engineeven in extremely cold weather.

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specification, but it will be understood that anymodifications within the scope of the claims may be made in theconstruction without departing from the principle of the invention orsacrificing any of its advantages.

What I claim is:

1. An attachment of the class described comprising a hollow body havinga discharge terminal at one end and an upturned receiving cup at itsother end, and fuel containing means carried by said body and positionedto direct the heat issuing therefrom around said body.

2. An attachment of the class described comprising a hollow body havinga discharge pipe at one end for connection with the air intake of acarbureter or with the manifold of an engine and equipped at its otherend ith an upturned receiving cup,

said body having at its opposite sides near the bottom thereof alaterally extended fuel containing tray.

3. A device of the class described com- 5 prising a hollow body havingan intake at one end and a discharge at the other, a fuel containercarried thereby adjacentthe bottom thereof, and a handle connected withthetop for convenient manipulation of the device. 10

In testimony whereof, I aflix my signature hereto.

EDWARD D. HISCOCK.
